In previous research, a consumer's decision to continue a service relationship is traditionally conceptualized as a function of the integration of customers' current and past levels of utility from a given service experience. We argue that current and past service experience should be augmented by incorporating future utility considerations as well. We therefore develop a "forward-looking" model that incorporates both expected future use and anticipated regret on consumers' decisions to keep or drop a service. Strong empirical support is found for the hypothesis that expectations of high future use positively affect retention, over and above the effects of satisfaction. The results provide new insights into the antecedents of customers' perceptions of expected future usage. Customers appear to update their expectations of future use following an adaptive expectations approach. We also find support for the hypothesis that anticipated regret affects the customer decision. Consumers who are asked to anticipate regret associated with mistakenly discontinuing a service relationship are less likely to drop than those who are not asked to anticipate regret. As hypothesized, we find differential effects of anticipated regret for on-going services and transaction-based services. Taken together, the empirical findings support a forward-looking model of customer retention. The importance of incorporating these future-focused aspects into models of customer retention and marketing mix strategy is also discussed.
